To all 'whom t may concern:

Be it known that We, HARRY E. PATRICK, ANDREW J. PETERSON, and JOHN W.Balmes, citizens of the United States, residing at Evanston and Chicago,respectively, in the county of Cook and State of illinois, have inventedcertain new and useful improvements in Apparatus for Use in Assembling,Repairing, and Limbering Gas Engines of Various Types, oit' which thefollowing is a speciication.

Our invention vrelates to a combination machine adapted to be used inconnection With the repair, assembling and limbering of linternalcombustion engines. The primary obj ect of the invention is to provide amachine of the above character in which the supporting structure or' theoperating mechanism may be readily and conveniently equipped with enginesupporting devices and connecting elements, so that the said operatingmechanism maybe expeditiously employed in the performance of the severaloperations incident to the repair, assembling .25 or limbering ofinternal combustion engines of various types. p

In order to make extensive repairs on dif-y ferent types of engines,prior to our invention, it was necessary for the automobile servicestation or repair shop to be equipped with separate machines forperforming the several operations and in most cases require speciallyconstructed machines for each type of engine repaired or constructed.This condition required a large expediture for shop equipment and as aresult, of this disadvantage, many proprietors oi' service stations andrepair shops confined their repair Work to certain types of engines. Itis, theres fore, contemplated as one of the objects or' our invention toovercome the above disad vantages by providing a simple, compact andinexpensive structure which will perform the several operationsnecessary `when making extensive repairs on engines and which, due toits compactness in structure and adaptability to the constructions ofdiilerent types of engines, is particularly suitable 'for use inautomobile service stations and repair shops. i

- The invention consists in the .novel arrangements, constructions andcombinations of parts and devices rhereinafter, de-v scribed andclaimedfor carrying out the above 'stated objects and such other objectsas may appear from the following description.

VVehave illustrated our invention in con.-

Like characters of reference designate like parts in the several figuresof the drawings.

When internal combustion engines are constructed or have been repairedby rebabbitting the crank shaft bearings, the bearings areusually muchtoo tight to permit the engine to be operated under its own power. In.order to relieve` the binding. of these bearings they are burned in byrotating the crank shaft at a relatively low speed before the saidbearings have been lubricated. This operation may be performed inconnection with our apparatus while the engine is `in the uprightposition, as shown in Fig. 2, or while it is in an inverted position asshown in Fig. 4. After the burning in operation has been performed theengine is preferably completely assembled and is operated at a higherrateofspeed to limber the bearings and such other connections of theoperativeparts that may be tight. `This operation may be convenientlyperformed by securing the assembled engine on the supporting stand inthe position shown in Figs. 3 or 9, and connecting the crank shaft withthe operating mechanism. If the engine is Vof the tractor type itispreferably secured to the supporting device shown in Fig. 3 with thelower section of the crank case removed. A sufficient quantity oflubricantY engine` in operating under itsL own power.

The apparatus consists of a base 25 providedv with a fiat table port-ion26 adapted to support an engine supporting stand 27 `which consists,asshown, in Figsjl, 2, 3,5 and 8, of a recessed `portion 28 havingflanges 29 to which the flange 3Q of the' upper section of the crankcase of the engine may be bolted or otherwise suitably se" cured. Therecess preferably inclines downwardly to an enlarged portion v3l whichis adapted to receive the balance wheel of the engine and tocontain thelubricant while'the engine isbeing subjected to the limbering actionpreviously referred to. in the drawings we have illustrated a suitablemeans for securing the engine to the supporting stand which consists,preferably, of rods 32-32 which are pivoted tostuds 33 33 on oppositesides of the recess as indicated at 28 andcarry at their upper end a bar34 which may be clamped down against the top of the engine block 35 bymeans of nuts 36-37. The inner end of the stand 27 is provided with ahousing 38 adapted to fit over the upper portion of the balance wheelof' the'engine and is preferably detachably secured to the stand bymeans of rkpivoted screw clamps 39 which fit between lugs 40 on thehousing. The stand 27 is preferably Af clamped to the table portion 26of the base with capacity for longitudinal adjustment by means of a bolt41 which extends through a boss on the bottom 42 of the stand and isprovided at its lower end with a bar 43, which engages the under surfaceof the lianges 44 of the table 26. A hand wheel 45, is threaded onto theupper end of the bolt and is adapted t-o be secured down against thesaid bossso as to firmly clamp the stand in position.

Vith certain types of engines, such, for example, as that used inlFordautomobiles, it is desirable to support the engine block in an invertedposition while performing the burning in operation. Y lnFigs.l 4 and 6we have shown a lsuitable device for supporting the engine block in thismanner, which device consists of a hollow block 46 provided with guidingflanges 47 which fit over the guiding flanges 48 of the table 26 'so asto prevent any lateral displacement of the supporting block. This blockis also prevented from being longitudinally displaced by means of adowel-pin 49 which is secured in the lower flange 47 of the block andadapted to fit into a suitable counter bore in the table 26. y Theengine is preferablv secured in in= verted position on the block 46 bymeans of a clamping device consisting of rods 50-50 having hooks attheir lower ends which engage eyelets 51-51 on opposite sidesof the base25 and provided at their upper ends with a connecting bar 52. A screw 53is threaded into a lcentral reinforcing boss 54 of the bar 52 and has atits lower enda swivel cap 55 adapted to engageone of the crank shaftbearings. Y The upper end of the screw C55 is bent `at right angles toprovide a hane 56. Y

When performing Lthe burning in or linibering operations the crankVshaft of the engineisconnected to the operating mech` anism supported onthe base. This mechanism consists of a shaft 57 supported at one end ina bearing 58 formed in an upstanding leg 59 of thebase and at the otherend in a bearing 60 formed in one side wall of a casing 61 whichencloses the gears for varying the'speed of mechanism. A pulley 62 isrevolubly mounted on the shaftI 57 and is operatively connectedtherewith, when desired, by means of a friction clutch mechanismconsisting of a hub portionY 63 which is keyed to the shaft as indicatedat 64 and is provided with three radial arms 65 having suitable guideways for friction shoe elements 66. YThese elements are operativelyconnected with a collar 68 slidably mounted on the hub 63 and formedwith a groove 69 into which extend the studs 70 of a fork 71. The lowerend of this fork is fixed to a shaft 72 mounted on lugs 73 llO VLio

belt pulley so as to yclutch the pulley and shaft together. For thepurpose of permitting the shaft to be rotated by hand ,in

dependent of the pulley 60, theV radial arms G5 of the clutch-areconnected toa hand Wheel 75. With this arrangement, theshaft may bereadily rotated by hand when the clutch mechanism is disconnected from'the' pulley 60. The inner end of the shaft 57 is provided with a counterbore 7 6 which receives a studA4 77 formed in the end 'of a shaft 7 8.This shaft is in linear alignment with the shaft 57 and carries at itsouter en'dk a connecting element 79 provided with studs 80 adapted to'fit into the usual kapertures of the crank shaft disk 8l Which'supports the balance Wheel of a Ford engine. kThe shaft 78 is supportedin a twov 1part bearing 82 and is prevented from moving longitudinallylby the'hub of the connecting element 79 anda shoulder 83 on the shaft;l-Vhenl performing the -limbering operation on the engine itis desirableto operatethe'engine at a higher rate of speed such as would be obtainedby a direct connection between shafts 57 and 78. This direct. connectionis preferably effected byV means of a gear 84e, vvhichis slidablysupported on a square portion 85 ofthe shaft 78. This gear is providedWith clutch teeth 86 adapted yto engage the clutch teeth 87 on a gear 88secured vto the inner end ofthe shaft 57; The sliding movementof thegear 84 is effected by means of a'yoke 89 which is secured to a slidingrod .90 and lprovided with studs 91 Which extend intoan annular groove92 formed in the hub ofthe, gear 84. y The rodV preferably extendsthrough the cap ofv the casing 61y and `is operatively'connected toalever' 93. When it is desired tooperate the engine at a reduced rate ofspeed, such for example, as required when burning in the bearings of theengine, the shafts r57 and 78 Aare oonnectedpby means of a spool gear 94on a shaft 95. The larger gear 96 of the spool meshes with the gear 88and the smaller gear 97 of the spool meshes with the gear 84.' After theburning in operation has'been performed the engine is vremoved from themachine and the balanceV Wheel is secured' to the crank shaft and, ifdesired, the engine may be completely assembled.' The engine is thenagain secured to the supporting stand 27 as indicated in Fig. 3 and theconnecting element 79 is operatively engaged vvithrthe balance wheel. Itwill beunderstood that When limbering the engine the balance Wheelpreviously applied to the crank vshaft requiresthe stand 27 of the baseto be adjusted longitudinallyvso as to permit the connecting element 79and the balance wheel 98 to be properly engaged. 99 in the housing 38and the recessed portion 31 `ofthe stand 27 preferably fit over theoutersurfacey of thewtvvo piece bearing 82 so 'as to permit the saidstand to be readily slid.l into position on the table portion 26. Thisvopening, it will be noted, is substantially closed bythe bearing 82under conditions as illustrated in Fig. 2 and by the head 79 underconditions as illustratedy inFig. 3 sorasto prevent any of the oil inthe recess 31 from being splashed out during the limbering operation.

For the purpose of permitting an engine,

which has been entirely assembled, to be limbered up ortested, We haveprovided a removable supporting stand such as that shown in Fig. 9 andldesignated generally by the reference character 100. This stand may besecured on the table 26 of the 'base in substantially the same manner asthe stand'27 and consists preferably of `channel supporting yposts 101atopposite sides of the base adapted lto receive the suspension lugs ofthe motor casing and with a central up-V right support 102 lwhichsupports one end of the casing. cured in position on these posts byscrew clamping devices 103 adapted to be s'crewrd down against thesuspension lugs of the engine and the vrclamping device 104 adapted toengagefthe bearing element 105 of the engine casing.VV The position ofthe engine may be adjusted in the supports 101-102 by means of a pivotelement 106 the lower end of which is bi'furcated' and lextends onopposite sides of a st`ud-107 108 designatesL f a handnutvvhichis'threadfed on the stud`l07vr and adapted tof be screwed down againstthe bifurcated yportion of the pivot element 106 so asy to `4 raiseor`lower the engine as desired.

Thile certaink specific structures have been i so described inconnection With our preferred embodimentit Will be obvious that' certainmodifications might4 be made Without ydeparture from our invention. W ethereforek do not Wish to limit ourselves to the exact structure 'shownand described eX- cept in so Vfar as specific limitations mav appear inthe appended claims.
